Smooth Path Hunting

You are analyzing a drone's altitude data. To ensure stable flight, you need to find the longest contiguous sequence of readings where the 'Total Variation' is within a budget V. Total Variation is defined as the sum of the absolute differences between all adjacent pairs in the window. Input Format: - The first line contains an integer V (the maximum variation budget). - The second line contains a space-separated sequence of integers representing altitude readings. Output Format: - A single integer representing the length of the longest such window. Example: Input: 3 1 4 5 5 7 Output: 4 (Explanation: Window [1, 4] variation is 3. Window [4, 5, 5, 7] variation is |5-4| + |5-5| + |7-5| = 1 + 0 + 2 = 3. Length is 4.)
